The technical scheme of the utility model is further described below with reference to the examples and the accompanying figures 1-2.

Example 1

An adjustable deadbolt comprising: fixing base one 1 and fixing base two 2, fixing base one 1 is fixed in on the door, fixing base two 2 are fixed in on the door frame, be equipped with vertical spout 11 on fixing base one 1, be provided with sliding sleeve 12 in the vertical spout 11, be equipped with slide hole 13 in the sliding sleeve 12, the slide is provided with movable rod 14 in the slide hole 13, be equipped with fixed cover 21 on fixing base two 2, fixing base one 1 bottom threaded connection has down ejector pin 3, lower ejector pin 3 upper end sets up in vertical spout 11, fixing base one 1 top threaded connection has last ejector pin 4, last ejector pin 4 lower extreme sets up in vertical spout 11.

As shown in fig. 1-2, the use principle of the utility model is as follows: according to the conventional installation mode, the first fixing seat 1 and the second fixing seat 2 are respectively installed, when the door is settled in the actual use process, the movable rod 14 cannot be smoothly inserted into the fixed sleeve 21 or cannot be inserted, the positions of the upper ejector rod 4 at the upper end and the lower ejector rod 3 at the lower end are adjusted, the position of the sliding sleeve 12 positioned in the vertical sliding groove 11 is adjusted, the sliding sleeve 12 is clamped and fixed, the sliding sleeve 12 and the fixed sleeve 21 are always kept on the same axis, the movable rod 14 is smoothly inserted into the fixed sleeve 21, and the adjustment is simple and efficient, so that the manual adjustment timeliness is reduced.

As a further preferred embodiment, two groups of vertical sliding grooves 11 are symmetrically arranged, a baffle 15 is fixed at the top of the vertical sliding grooves 11, the upper ejector rod 4 is arranged in the baffle 15 in a threaded manner, and two groups of lower ejector rods 3 and upper ejector rods 4 are symmetrically arranged in a single vertical sliding groove 11. As shown in fig. 2, the detachable baffle 15 at the upper end is arranged to facilitate the sliding sleeve 12 to be installed in the vertical sliding groove 11, and meanwhile, the vertical sliding groove 11 is a T-shaped groove, so that the sliding sleeve 12 cannot move forwards and backwards, and the stability of the sliding sleeve 12 is ensured; simultaneously, the two groups of lower ejector rods 3 and the upper ejector rods 4 can further improve the stability of fixing the sliding sleeve 12.
